lol wtf are talking about? being close to her victims is her modus operandi, being alone with the teacher, with the idol without getting caught in a camera, with the grandpa in a hospital, with the little brother in an apartment, all of this means she is confident enough that she can win in the situation and not be caught. If your criticizing and dont like the author's method of writing you should have just drop the manga along time ago just like some of the readers in earlier chapters with something similar reason to yours, we are way pass that already.
